HARRY H. FUSSEY, OF MEDIX RUN, PENNSYLVANIA, AND ALBERT BROWN, OF ANDOVER, NEW YORK.

LADDER.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed. April 1, 1908. Serial No. 424,592.

T 0 all whom it may concern:

Be it known that we, HARRY H. FUssEY, residing at Medix Run, Elk county, Pennsylvania, and ALBERT BROWN, residing at Andover, Allegany county, New York, have invented certain new and useful Improvements in Ladders; and we do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to foldable ladders used as fire-escapes; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of a portion of the ladder. Fig. 2 is a side view of the same.

A is a support, such as a window-sill.

B is the top bar of the ladder which is pivoted to the sill A by staples b, or in any other approved manner.

C are the side-bars of wire which are con nected to the bar B, and which have eyes 0 at their lower ends.

O are diagonal braces formed of crossed wires and secured to the middle part of the bar B and to the eyes 0.

The ladder proper consists of a series of wire links D having eyes (Z at their tops, and eyes e at their bottoms.

E are loops formed in the twisted portions of the wires at the lower parts of the links, and F are the rungs or treads which are inserted in the said loops. The rungs F are formed of steel or cast-iron, and they are angle-shaped in cross-section. The rungs have notches f at their end portions which engage with the loops.

In order to place the angle-iron rungs so that they will be very strong and at the same time afford the best possible hold for the hands and feet, the apex g of each bar is placed at the rear next to the wall, shown by the line G in Fig. 2. This brings the hollow of the bar next to the palm of the hand, and the edge of the bar is held away from the wall and toward the front of the ladder.

hen the ladder is not in use, it is folded up, and placed on a hook ll which projects from the window-sill.

What we claim is:

1. In a ladder, the combination, with a series of wire links arranged in pairs and provided with loops between their end portions, of metallic rungs having notches in their end portions which engage with the said loops, said rungs being thereby prevented from revolving or sliding longitudinally.

2. In a ladder, the combination, with a series of wire links arranged in pairs, of rungs formed of angle-shaped bars having notches in their end portions for engaging with the said links, each bar being arranged with one side edge uppermost.

3. The combination, with. a support, and staples projecting therefrom; of a top-bar pivoted in the said staples, side-bars of wire secured to the said top-bar, diagonal wire braces secured between the said top-bar and side-bars, and a foldable ladder comprising a series of links arranged in pairs and pivotally connected with the said side-bars, and rungs secured between the said pairs of links.

In testimony whereof we affix our signatures, in presence of two witnesses.
